Possible Causes

Safety first: Unplug the cooker.

Dry the panel: If the panel was recently wiped or exposed to steam, leave the cooker unplugged for several hours to dry completely.
Clean surface: Wipe the control panel with a soft, dry cloth. Avoid spraying cleaner directly onto the panel.
Check for stuck buttons: On mechanical-button models, press each button to ensure it returns fully and is not jammed by debris.
